Return URLS from php string -

i have php array of strings looks this

array (     [1] => lorem ipsum dolor sit amet http://www.google.com/search?q=stackoverflow consectetur adipiscing elit.     [2] => phasellus tempor vehicula fringilla. www.google.com/search?q=stackoverflow&ie=utf-8     [3] => google.com/search?q=stackoverflow&ie=utf-8 aenean in cursus libero. ); 

urls sorts of forms, need array of links. this:

array (     [1] => http://www.google.com/search?q=stackoverflow     [2] => http://www.google.com/search?q=stackoverflow&ie=utf-8     [3] => http://www.google.com/search?q=stackoverflow&ie=utf-8 ); 

the code you:

$pattern = '/((https?|ftp)\:(\/\/)|(file\:\/{2,3}))?(((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?))|(((([a-za-z0-9]+)(\.)?)+)(\.)(com|org|net|gov|mil|biz|info|mobi|name|aero|jobs|museum|[a-z]{2}))([\/][\/a-za-z0-9\.]*)*([\/]?(([\?][a-za-z0-9]+[\=][a-za-z0-9\%\(\)]*)([\&][a-za-z0-9]+[\=][a-za-z0-9\%\(\)]*)*))?/';  $a = array(     'lorem ipsum dolor sit amet http://www.google.com/search?q=stackoverflow consectetur adipiscing elit.',     'phasellus tempor vehicula fringilla. www.google.com/search?q=stackoverflow&ie=utf-8',     'google.com/search?q=stackoverflow&ie=utf-8 aenean in cursus libero.', );  $urls = array();  foreach($a $line) {     if(!preg_match($pattern, $line, $match))         continue;      $urls[] = $match[0]; }  var_dump($urls); 

the regular expression taken here , corrected bit.
